Scan Tool Clear Command

If you are using a generic scan tool to clear commands, be aware that there is only one setting for clearing the PCM, and it clears all commands at the same time (CKP pattern learn, idle learn, readiness codes, freeze data, on-board snapshot, and DTCs). After you clear all commands, you then need to do these procedures, in this order: PCM Idle Learn Procedure ; CKP Pattern Learn Procedure ; test-drive to set readiness codes to complete - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS , or How to Set Readiness Codes .
